Abstract Background: Cardiac catheterization as a cardiac diagnostic test may lead to anxiety and fear in patients. High levels of anxiety can cause changes in the hemodynamic parameters of patients. Foot reflex zone massage is a method of alternative medicine may be useful in the reduction of anxiety. The aim of this study was to investigate the effect of foot reflex zone massage on anxiety ...
Background and purpose: Candidates for cataract surgery have high anxiety and worry for various reasons which may cause changes in their hemodynamic parameters. Maintaining hemodynamic stability during anesthesia and surgery is very important. This study aimed at comparing the effects of listening to nature sounds and lavender inhalation on hemodynamic parameters in patients undergoing cataract...
Cortical neurons with similar properties are grouped in columnar structures and supplied by matching vascular networks. The hemodynamic response to neuronal activation, however, is not well described on a fine spatial scale. We investigated the spatiotemporal characteristics of microvascular responses to neuronal activation in rat barrel cortex using optical intrinsic signal imaging and spectro...
Since antiquity, the human arterial pulse represents an important parameter in the clinical assessment. Besides being routinely assessed in the medical practice, such pulse is not observed in its completeness yet, once many of the data obtained through it cannot be evaluated using conventional methods. Taking into account such methods, the measurement of arterial blood pressure using sphygmoman...
Conventional hemodynamic measurements and Doppler echocardiography were used to assess ventricular physiology of the human cardiac allograft and to examine the influence of pertinent clinical factors on chronic myocardial performance. Sixty-four patients (18-55 years old; mean, 39 years) undergoing routine annual hemodynamic assessment were studied. Blood-flow velocity properties across the mit...
BACKGROUND Right ventricular (RV) diastolic function has been associated with outcomes for patients with pulmonary hypertension; however, the relationship between biomechanics and hemodynamics in the right ventricle has not been studied. METHODS AND RESULTS Rat models of RV pressure overload were obtained via pulmonary artery banding (PAB; control, n=7; PAB, n=5). At 3 weeks after banding, RV...
